E-Commerce Website Development with Printify Integration

I'm looking to build an online variety store focused on clothing and shoes, with future expansion to eBooks. The site needs to connect to Printify for product fulfillment, and should be designed with a category navigation system for product search.

Key Requirements:
- Capacity to host 200 products initially, with scalability options for future growth
- Printify integration for seamless product sourcing and shipping
- E-commerce functionality that allows for secure online transactions
- User-friendly interface with a category navigation system for easy product search

Future Considerations:
- The site should have the ability to upload eBooks (with images and audio) in the future
- I need guidance on maintenance costs and requirements for the site post-launch
- Training on how to do uploads and corrections myself

Skills and Experience:
- Expertise in website development, preferably with experience in creating e-commerce sites
- Proficiency in integrating third-party services like Printify
- Knowledge of eBook uploading and site requirements for digital products
- Experience with WordPress/WooCommerce platform is a must, as that's my preferred choice
- Strong communication skills for training and explaining technical aspects in an understandable way
